본 논문에서는 기호별 XOR 연산을 기반으로 한 복호화 및 순방향 기반 양방향 중계의 시스템 성능을 조사한다. 이 기술은 중계국에서 변조 및 코딩 방식을 선택하는 데 더 많은 자유를 제공하고 전송 병목 현상을 크게 완화합니다. 그러나 두 링크의 변조 차수가 서로 다를 경우 성능 저하가 발생합니다. 이러한 영향을 완화하기 위해 우리는 MCS 레벨을 겹쳐서 중복 변조 코드 체계와 함께 반복 코딩 체계를 활용합니다. 이를 위해 시스템 레벨 시뮬레이션을 통해 제안된 방식이 비트별 XOR 기반 양방향 중계에 비해 약 43%의 용량 이득을 달성하고 기호별 XOR 기반 양방향 중계에 비해 추가로 10%의 이득을 제공한다는 것을 입증했습니다.

Abstract: In this paper, we investigate the system performance of decode and forward based bi-directional relaying based on symbol-wise XOR operation. This technique gives more freedom in selecting the modulation and coding scheme at relay stations, and significantly relaxes the transmission bottleneck. However, the performance degradation occurs when the modulation orders of both links differ from each other. To mitigate such an impact, we exploit a repetition coding scheme in conjunction with a redundant modulation code scheme by overlapping MCS levels. To this end, a system level simulation proves that the proposed scheme achieves about 43% capacity gain over bit-wise XOR based bi-directional relaying and gives additional 10% gain over symbol-wise XOR based bi-directional relaying.

AB - In this paper, we investigate the system performance of decode and forward based bi-directional relaying based on symbol-wise XOR operation. This technique gives more freedom in selecting the modulation and coding scheme at relay stations, and significantly relaxes the transmission bottleneck. However, the performance degradation occurs when the modulation orders of both links differ from each other. To mitigate such an impact, we exploit a repetition coding scheme in conjunction with a redundant modulation code scheme by overlapping MCS levels. To this end, a system level simulation proves that the proposed scheme achieves about 43% capacity gain over bit-wise XOR based bi-directional relaying and gives additional 10% gain over symbol-wise XOR based bi-directional relaying.
